It's probably any one or all of a couple of things. Shakey hands is a good guess. When you're zoomed in a real tight on something, any small movement of the camera is going to result in motion blur. Try a tripod.
Also, some of the less-capable digital cameras have a real hard time auto focusing at very short distances. I don't know if your camera has a "macro" mode, but try engaging that, and see if your camera can lock on. Otherwise, look up the specs on the minimum focusing distance, and adhere to them. As a last resort, you can try manual focus, if your camera has it. (Though I've found that manually focusing lower-end digicams is tough.) |
